Computer Mouse for Different Modes of Use

2. The computer mouse according to claim 1, comprising at least one sensor for detecting a mode of operation by a user, wherein the circuitry is configured to, in a first detected mode of operation, and in response to a displacement operation by a user, output a first signal for causing a user interface display of a computer system communicating with said mouse to show a first movement in a first direction in a displayed image and, in a second detected mode of operation, and in response to said displacement operation by a user, output a second signal different from said first signal for causing said user interface display to show a second movement in a second direction in the displayed image, said second direction being different from said first direction.

3. The computer mouse according to claim 1, wherein said mouse buttons have seams along respective outer perimeters, except at the flexible hinge areas which are seamless on the sides of the button caps facing each other and facing neighboring portions of the mouse button face forming the touchpad surface area.

4. The computer mouse according to claim 1, wherein said mouse buttons are operable by pressing a respective area of a respective button, causing the respective button to hinge about the respective flexible hinge area on the side of the respective button cap.

5. The computer mouse according to claim 1, wherein portions of the caps of the mouse buttons also form portions of the touchpad surface area.

6. The computer mouse according to claim 2, comprising at least four mouse buttons arranged symmetrical about a symmetry plane perpendicular to said surface plane.

7. The computer mouse according to claim 6, wherein, in a first mode of operation a first pair of the at least four mouse buttons function as a standard left and right mouse button; and in a second mode of operation, the other, second pair of the at least four mouse buttons function as a standard left and right mouse button.

8. The computer mouse according to claim 7, wherein said thumb face is also symmetrical about the symmetry plane and the mouse is elongate in a horizontal longitudinal direction perpendicular to the symmetry plane, wherein the mouse at half height, is at least 70 mm long in said horizontal longitudinal direction.

9. The computer mouse according to claim 1, the touchpad surface area comprises a central area of the mouse button face that is separate from any areas forming the mouse buttons surrounding the central area.

10. The computer mouse according to claim 1, wherein the mouse button face is slanted backward so that it is oriented at an average enclosed angle between the mouse button face and the surface plane of more than 60° degrees.

11. The computer mouse according to claim 10, wherein the mouse button face is slanted backward so that it is oriented at an average enclosed angle between the mouse button face and the surface plane of between 70° and 80° degrees.

12. The computer mouse according to claim 10, wherein the mouse button face is hollow, wherein lower mouse buttons on the mouse button face slant more than upper buttons on the mouse button face.

13. The computer mouse according to claim 6, wherein said mouse button face and said thumb face are each symmetrical about a common symmetry plane perpendicular to said surface plane.

14. The computer mouse according to claim 13, wherein said second movement in response to said displacement operation in a displacement direction in said second mode of operation is also caused by a displacement operation in said first mode of operation in a direction that is mirror symmetrical about said symmetry plane to said displacement direction, wherein a scrolling direction on the user interface display is determined based on a combination of a direction of input by the finger of said user hand moving along the surface or scrolling input interface of the sensor, and the mode of operation, wherein in a left handed mode of operation, the direction of an input that causes scrolling in up-down direction on the display is mirrored about the symmetry plane compared to right handed mode of operation.

15. The computer mouse according to claim 2, wherein the mouse buttons are used as the at least one sensor for detecting the mode of operation.
